The effect of the Raman-pulse duration related to the magnetic field gradient,as a systematic error,is playing an important role on evaluating the performance of high-precision atomic gravimeters.We study this effect with a simplified theoretical model of the time-propagation operator.According to the typical parameters,we find that this effect should be taken into account when the gravimeter reaches an accuracy of 10-10g,and the larger the pulse duration is,the more obvious the systematic effect will be.Finally,we make a simple discussion on the possibility of testing this effect.
